Abstract

In some embodiments, a subsurface wiping plug apparatus includes an internal bore that extends for less than a length of the apparatus. A ported case encloses internal components of the apparatus such that each port of the case is configured to couple the internal bore to an external side of the case. A plug capsule is coupled to an end of the ported case. The plug capsule contains an internal wiping plug that is releasable by internal pressure.
